Phonological encoding in apraxia of speech and aphasia.

ABSTRACT:

Background

Apraxia of speech (AOS) is considered a speech motor planning/programming disorder. While it is possible that co-occurring phonological impairments exist, the speech motor planning/programming deficit often makes it difficult to assess the phonological encoding stage directly. Studies using on-line methods have suggested that activation of phonological information may be protracted in AOS (Rogers, Redmond, & Alarcon, 1999).

Aims

The present study was designed to investigate the integrity of the phonological encoding stage in AOS and aphasia. We tested two specific hypotheses, the Frame Hypothesis and the Segment Hypothesis. According to the Frame Hypothesis, speakers with AOS have an impairment in retrieving metrical frames (e.g., number of syllables); acco
